dieIZ to move the die 1I2 into the Topen. positiony in.Fig.1.* o Theupper operating handle r8 extendsk into ya socket in a slidable pivotedcam head 4I)` in'which The head 40 is providedwth a^narrow portion 4Iwhich operates between inwardly extendingr opposed flanges 42 and 43 `onthe upper edges of shoe plates 44 yand 45 secured to ythe bodyportion-by screws46 as indicated in some of the vfigures. This head isof the general form shown in the' gures and its depending portion 56isprovided with a. wide bearing portion 5I carrying a pivot pin52operating in slots 54 and 55. in the shoe plates 44 yand 45, This wideportion provides -zshoulders vcooperating with the` opposed fianges 42and 43 tolimit the opening movement, of the operating handle 8. Theforward end ofthis wide portion is provided with a cylindrical face 60bearing in a concave scat 6I inthe rear end of the movable die I2, andalining the groove 20 of the movable die I27with vthe groovefl9` of thestationary die II. t The rear end of the enlarged portion 5I is'providedwith an arcuate eccentric carn face 62 cooperating with a backerfroller63 supported by a leaf A'spring 64 secured to the body portion by. means,of l'a bar plater 65 tenoned `in the shoe plates 44 and45.- The backerroller is retained in position by a bar plate 66 tenoned in the .shoeplates as shown.

y:The roller cooperates with a roller backer block 10 provided withrectangular guide lugs "II, 12, operating in horizontal slots in theshoe it may be adjusted in the slots in the shoe plates to control theforward limit of movement of the movable die during its forwardmovement. This adjustment screw is rotated by means of the lower handle1 to which it is secured by a transversely extending pin '15. The frontface of the roller backer is arcuate and substantially concentric withthe pivot pin 52 so that the cam face on the rear ofthe head 5Ioperating on the roller will cam the head and move the die I 2vforwardly to swage and compress the end fitting on the cable.

In the use of the swaging tool, the lower hxiirL.` ".I

dle 'I is rotated to control the operated position.4 of the movable diein accordance with the said body portion, an opposed movable diesupported in said body portion, a roller supported v. in said bodyportion, a cam between said roller vfg'rand said n'iovable` die, ahandle for operating amount of reduction desired to be'eifectedfduringthe lrstseries of swaging operations. The dies are then separated andthe cable with the blank i Y tting on it is passed through the slots32and 33 of the cable supporting bracket 3I into the extensions 34 and 35of these slots vand the blank tting is seated in the die face kI'I ofthestatio'nary die II. These diesk are .closed and opened and the cableis rotated until thedies have op-` erated at the required number ofdifferent points circumferentially of the tting after which theY lowerhandle is turned clockwise as viewed from the right of Fig. 1 to advancethe roller backer 'Il the head`5I of the upperhandlef and the movabledie I2 afterwhich a second series of operations is performed as beforeand so forth and for the last series of operations the roller backer isadvanced to cause the movable die to engage the stationary die at thelimit of `its forward movement.

It is obvious that this invention is not limited to the shape of thefaces of the dies and that these faces may be given yany desired Vshapede.

pending upon the original and/or desired ilnal cross sectional shape ofthe fitting or the shank of the fitting and that a'swaging tool built.in ac, cordance with this invention may be used to apply fittings notonly to an end but alsoat. any point along the length of a cable oryanyoth'er elongated member and to connect anymember to or about anothermember regardless of the relative axial dimensions or lengths of themembers and to change the cross sectional shapes of,

perform other operations on, articles of various kinds.l
